This is really funny stuff, sorry I can't help but laugh.
It's Vista SP2 - only it's called Windows 7. You guys and gals are cracking me up. And exactly what makes you think this OS is gonna be any better than the failed Vista?? It's based on the Vista code base.
Yes there is supposed to be a Vista SP2 -- NO, it will not include DX11. But does it matter? Very few games are developed for DX10, and none for DX10.1 so what is the point of DX11?
Mac OS X is doing just fine in sales, in fact it is slowly but surely taking away Microsoft's dominant OS market share.
Apple are releasing a new OS BEFORE Microsoft, it's $179 - one version does all. There will be some real changes in the OS, full 64bit support is one.
People buying new computers are people buying laptops, guess who sells the most laptops -- yes that would be Apple. Heck, if you don't believe me, just go to your local coffee shop and look around, oh you see some Mac laptops....hmmm...what do ya know.
Games are gonna be consoles, the PC is gonna die for so many reasons -- software piracey being one. Apple will survive cause you can still pretty much do whatever the hell you want on OS X. And the we have free open source, most of which works best on OS X or Linux. Yes that is FREE and PC dweebs love the sound of FREE.
Unless Microsoft make some fundamental business changes, they're just pushing out the same garbage.
